SpeedVitals▲829Hi HN, I’m Kashish, one of the co-founders of SpeedVitals, a platform for testing & monitoring website performance with a major emphasis on Core Web Vitals.

But now, we have developed a Real-User Monitoring platform that doubles up as a Web Analytics tool. One major feature we have that most RUM tools lack is Performance Audits.

PageSpeed Insights only audits one URL at a time, which makes comparing pages slow and repetitive. I built a small free tool that lets you run Lighthouse audits across multiple URLs and compare SEO, performance, and accessibility scores side-by-side.
